Mounted Positive Achromatic Lens, D=40mm, F=500mm, VIS-A, United Optical Technology Co., Ltd (CAT#: STEM-OP-1907-YJL)

Mounted Positive Achromatic Lens, D=40mm, F=500mm, VIS-A, model 145228, is manufactured by United Optical Technology Co., Ltd.
Achromatic lenses, also known as doublet lenses, are made of two lenses made of materials with different refractive indexes and dispersion rates. For better performance, the side with a larger radius of curvature (the flat side) should face away from the collimated beam. In addition, the achromatic design also helps light sources with a wide wavelength range (composite light sources) to maximize imaging aberration and reduce spherical aberration and chromatic aberration. Achromatic lenses produce clearer images than optical systems using a single lens, further improving the optical performance of the lens. Achromatic lenses are suitable for a variety of applications such as fluorescence microscopy, image relay, detection or spectroscopy. Achromats create smaller spots of light than monolithic lenses.
